How do I make a unique component on mac (free web version)

I can’t figure out how to make a unique version of an existing component. Mac OS. Free web version.

Right click (Context click) on the instance of the component and choose Make Unique.

No right clicking with the mac mouse.

Context click: Hold Ctrl while clicking.

SketchUp works a whole lot better and more efficiently with a simple 3-button mouse. Left, right, center under scroll wheel.

Bingo! Thank you!

There’s a good chance your mouse has two buttons and you just haven’t configured it to use the other one in System Preferences / Mouse. Even Apple has put two buttons on their mice since about 2005. Unless your mouse is older than your computer, it will have two buttons as a Mac that old wouldn’t run Catalina.
Change that option for now, then get a 3 button mouse as Dave said.
